The complementary implementreceptacle 604 would also have a corresponding number of grooves (notillustrated) or shape to complementarily accommodate and engage theimplement spline 223. In a further alternative exemplary embodiment asillustrated in FIG. 7, the implement spline 223 on second plate 211 mayinstead be connected to the tractor 601 via a corresponding orcomplementary connector on the tractor 601; additionally, in thealternative exemplary embodiment as shown in FIG. 7, the housing 203 onthe first plate 209 may be connected to the implement or trailer 603 viaa corresponding or complementary extension on the implement or trailer603.

An exemplary embodiment of a method of use for the subject disclosedembodiment as illustrated in the figures follows. To connect or engageplates 209, 211, the plurality of connectors 213 are inserted into thelarger open end 210 a of the plurality of tapered openings 210.Subsequently, the first plate 209 and the second plate 211 are twistedor rotated in relation to each other in a first direction; and theplurality of connectors 213 are slid, moved or maneuvered from thelarger open end 201 a of the plurality of tapered openings 210 to thesmaller open end 210 b of the plurality of tapered openings 210. Theconnector top 213 a, being of a larger size than the smaller open end210 b of the plurality of openings 210, prohibits the removal of theplurality of connectors 213 from the smaller open end 210 b of theplurality of tapered openings 210. Additionally, at least a firstguideline 221 as inscribed on the circumference 228 a of the first plate209 is aligned with a second guideline 219 inscribed on thecircumference 228 b of the second plate 219. The locking shear pin stem215 b can now be threaded, engaged or inserted through the locking shearpin slot 216 and one or more of the locking shear pin holes 214. Theplates 209 and 211 are now prevented or prohibited from rotation inrelation to each other. The receiver or body 207 of the first plate 209may be already be engaged with the PTO shaft 602 prior to the plates209, 211 connecting as described above, or may be engaged with the PTOshaft 602 after the plates 209,211 have been connected. Likewise, theimplement spline 223 as extending from the fourth outer surface 226 b ofthe second plate 211 may also already be rapidly and removably engagedwith the implement receptacle 604 prior to the connection of the plates209,211, or the implement spline 223 and the implement receptacle 604may be engaged after the connection of plates 209,211 as describedherein.

To disengage, disconnect, separate or remove the plates 209 and 211 fromeach other, first the locking shear pin stem 215 b is unthreaded,disengaged or removed from the at least one locking shear pin hole 214from which the stem 215 b was engaged and also from the locking shearpin opening or slot 216 from which the locking shear pin stem 215 b wasalso engaged. Now the first plate 209 and the second plate 211 can betwisted or rotated in relation to each other in a second direction(opposite to the first or initial direction). Subsequently, theplurality of connectors 213 are slid, moved or maneuvered from thesmaller open end 210 b of the plurality of tapered openings 210 to thelarger open end 210 a of the plurality of tapered openings 210. Then,the plurality of connectors 213 can be removed or disengaged from thelarger open end 210 a of the plurality of tapered openings 210 and theplates 209 and 211 are fully disengaged.

In certain exemplary embodiments having a locking spring loaded pull orshear pin 215, the locking spring loaded shear pin 215 may be initiallyinserted into, or engaged with the locking shear pin slot 216 prior toengaging the connector or stud 213 to the plurality of tapered openings210.
